CONFIDENTIAL DATA TRANSPORT IN NOISE IMAGE
Abdurrahman HAZER İbrahim ÖZER Remzi YILDIRIM
AbstractIn this work, cryptography has been developed to ensure that confidential information is communicated securely. As a method, a randomly generated phase mask and a grey level picture made entirely of noise is used. The information that is corrupted in phase is placed in this noisy image according to a predetermined algorithm. First of all, the image is closed with a randomly generated phase mask and then the pixel values of the image whose phase value is completely corrupted are scattered into the carrier by sliding along with certain mathematical operations. In order to recover the encrypted image and information, carrier and randomly generated phase keys are used respectively. It has been tested that the reliability of the algorithm developed with two keys and robustness of the algorithm to noise attacks. In addition, the reliability of the developed algorithm is also tested with techniques such as correlation, histogram and contrast stretching.
